` MUSTEE, a. citizen of the United States, re-

siding at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Oil-` Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to im rovements in oil-burners, and consists in t ev novel construction, combination, and arran ement of devices hereinafter described and c aimed.

The object of the invention is to improve the construction and operation of devices of this character and thereby render the same more efficient and durable and less expensive.

The above and other objects, which will appear as thenature of my invention is better understood, areaccomplished by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the improved oil-bu'rner, parts being broken away to more clearly illustrate the construction.

Fig. 2 is a vertical sectional view through the same. Fig. 3 is a detail sectional view taken on the plane indicated by the line 3 3 in Fig. 1. Fig. 4 is a perspective view of one of the braces or brackets for'sup orting the air` draft ring or collar and the drum, and Fig. 5 isa similar view of the spring for holding the wick in its carrier. Y

The embodiment of the invention shown in the drawings is in the form of anA oil-burner adapted for use on a stove and havin a body or reservoir 1, to lwhich oil is su plie from a tank or other source of supply t ough a supply-pi e 2. The reservoir or oil-receptacle 1 is in t e form of a hollowy cylinder having in-- ner and outer walls 3. v4 connected at their bottoms to p The inner cy to an inwardly-extendingannular shoulder 6 libr the reception of tlie flattened upper end of a circular wick 7j which latter extends rovide a space 5 for the oil.

inder or wall 3 has around its downwardly into the oil-space 5 between the two walls 3 4 and contacts with the inner wall 3. This wick is connected to and raised and lowered by means of a carrier 8, which is in the form of a cylinder provided with rows of perforations 9 and having adjacent to its bottom upon its inner face` inwardly-projectin spurs 10 to enter the wick. The latter is eld in engagement with said' spurs by a split circular spring l 1, which surrounds the inner wall 3, as seen in Fig. 2. The cylindrical wick-carrier 8 slides vertically in the oilspace 5 and is guided by its engagement with the inner face of the reduced upper portion 12 of the outer wall 4.

The wick is raised and lowered by turnin a hand-wheel 13, secured upon the outer en of a downwardly-inclined shaft 14, mounted for rotation in a tubular bearing 15, which projects into a casing 16, secured upon the outer face ofthe wall 4 of the body 1. Fixed upon the shaft 14 within the casing'or jacket 16 are two toothed Wheels 17, which engage the apertures 9 in the wick-carrier 8, and

, thereby lraise or lower the latter when the l hand-Wheel 13 is rotated.

Within the inner wall or cylinder 3 is an annular perforated ring 18, formed with a depending ilange 19, which is secured to the wall 3, and with an upwardly-projecting annularilange 20., ada ted to be engaged by the lower end of a per orated air-spreadercone 2l. rivet or the like 22 is a circular iiarme and alrspreader plate 23. The latter is dished'with its concave side lowermost and extends over the iiattened upper end of the wick 7, as clearly shown in Fig. 2.

Engaged with an annular shoulder 24, `formed by reducing the diameter of the upper portion of the outer wall 4 of the body A1, are a series of spacing and supporting brackets 25, each of which is formed from a single iece of heavy sheet metal by cutting and liending the same to rovide a substantially U-shaped body, which has at its top an outwardly-extending tongue 26. This U-shaped body of the bracket has its parallel ends or arms 27 projecting angularly from its con necting portion 23and shaped to engage the shoulder 24, and upon the outer facev of the connecting portion 2S is secured by 'a rivet or the like 29 an annular collar or sleeve 30.

Secured upon the top of this cone byL a IOO The collaror ring 30 is thus supported by and tures forme-f! in the ring or collar 30 and are The. tongues 26 of the brackets or braces 25 project through aper- IIO adapted to support the corrugated annular ring or flange 252 upon a cylindrical drum rlhis drum has at its top a similar corrugated flange or ring Ziel, which ex lends inwardly and reduces the opening in the top of said drum. The corrugated [lange 32 is provided at the bottom of the drum, so as to provide openings or spaces for the inlet ol' air into the druni around the outer side olI the ring or collar 30. At a suitable point in the vertical wall ol' the druni 33 is formed an opening adapted to be closed by a door 35, hingedly niounted, as at 36, and provided with mica, so as to permit the llame of the burn er to be seen l'roin Without the drum.

The oilreceptacle or reservoir l adjustably connected to the supj'ily-pipe 2 by pro-` vidiug upon the former an oil-inlet nipple or connection 8 adapted to receive one end ol' a coupling-.39, which has its outer end secured in the pipe 2, The coupling Z50 vis lorined with an annular flange 40 to engage the outer edge of the connection 38, and a lead washer or the like 3l is placed between the latter' and the coupling $39, as shown in Fig. 2. A The coupling is held lirnily against the connection 38 by a Vstrap orband 42, which is passed over the pipe 2 and has its apertured ends engaged with lugs 43, formed at opposite points on the connection 3S. Provided in the outer portion of the band 42 is a nut 44 to receive a set-screw 45, which has its inner end imping ing against the pipe 2. lt will be seen that when said screw 45 is screwed into the nut the ends of the band 42 will be drawn upon to draw the connection 35 into the coupling 39 and tightly against the washer Ll1.

The operation and advantages of the burner udll be readily understood. It will be seen that the annular shoulder 6 at the top of the inner wall of tube 3 will keep the oil from runiiingdown the inside of the latter and cause the condensed oil to be burned. It will also prevent the wick from burning unevenlv and prevent the air-draft frein cutting the llame from the wick. The necessary amount of airis fed to the llame at the top of the Wick through the perlorations in the ring and cone 2l, and the dellector 23 will direct it, so that the proper combustion is secured. The druin 33 produces a dralt through the space 31 and the corrugated portion 32 at :its bottoni, so that the necessary amount oll air is supplied to the burner.

Having thus described my invention, what l claim. as new, and desire to vsecure by Letters Patent,.is- 1 f Y 1. In an oil-burner, inner and outer wicktubes, the outer tube being shouldered near its upper end, a perforated collar around and at a distance from the upper ends ol said tubes, theupper end of said. collar being in# turned and extending above the said. tubes, substantially U-shaped brackets rigidly se cured to said collar, each bracket having its upper end bent laterally and projected through one ol the openings in the collar Vand the lower ends of the brackets resting on said shoulder, and a druni around the collar, the lower end of which is corrugated and bent inward and rests on the projecting ends of said brackets. ,A j
